Use FTDI TTL-232R-3V3 for Beaglebone Black

Post by huanngo »

Hi,
I bought a Beaglebone Black. I want to debug it with the USB‐to‐serial UART TTL serial cable. I've just ordered the
FTDI Serial TTL-232 USB Cable
PRODUCT ID: 70

https://www.adafruit.com/products/70

on Adafruit. I just want to make sure it's the right one. I'm confused about the voltage level. In the product description, it talks about the 3.3V, then 3V and 5V logic.
So please confirm I can use this product with Beaglebone Black.

Yes, it will work OK for BeagleBone Black as it is 3.3V power and signals:
The version we have is the 3.3V. The data signals are at 3V and the power line provides 5V. We suggest this for any product that needs FTDI cables. Because the cable is 5V-logic compliant, you can use it with 3v or 5v logic just fine - no level shifting required!.
